Letters Patent No. 111,334, dated January 31, 1871.

IMPROVEMENT IN STEM-WINDliNG WATCHES.

The Schedule referred to in these Letters Patent and makirig part of the same.

To all 'whom/it may concern Be it known` that I, WALTER H. Flrz GERALD, of Garlstadt, county of Bergen and State of New Jersey, have made a new and useful Improvement in Stem-Winder WVatches; and I hereby ydeclare the following to be a full and exact description, reference being had to the annexed sheet of drawing, which forms part of this specification.

Figure 1 shows a plan view of a watch-face, with a portion of the face-plate out away,..so as to exhibit ymy invention.

Figurefl is a cross-sectional elevation of the same.

My improvement relates to watches having thc ordinary stem-windeimovements.

In such watches the devices for setting the hands are thrown iu and out of gear with stem-winding gear, by means of a push-piece or pin projecting from the n n n i. -centerof the case. By pressing on thls pin the bandsetting gear is lthrown into connection with the winding stern. In myimprovemeutthis push-pin remains in the saine position as in ordinary stem-windin g watch es. rlhe whole; of the movementis also the same. But instead of operating the push-pin from the outside of tbecase fitis rmoved by a vlever on lthe side ot' the case, which lever is moved by a sleeve on the stem, which sleeve is moved by a projecting pin, bent at right angles on the bow-ring.

The following description will enable others to make and use my invention.

A is the case of the watch.

B, the stem.

C, the pendent bow.

H, the milled head for turning in winding or handsetting.`

1) a pin', bent at right angles, and projecting from the end of the bow.

d, the sleeve around the spindle y, to be pressed down by the pin p, ou turning the bow to theposition shown in g. 2.

The sleeve ll acts upon the iever f which moves the push-pin 71..

lhis'pin 7L is the same in position and function as the projecting pin in the ordinary stem winding watches.

vThe pin h moves the pivoted lever t, which moves collar m, so as to release the clutch a from the counter-clutch n', and throw the crown-wheel s'iuto gear with the hand-set pinions.

Then sleeve f7 is released by returning the bow to the position shown in iig. 1, the spring K acting on the pivoted lever i throws the collar m up to the positionshown in tig. 1, so that the'clntch n engages with the counter-clutch n', which brings into connection the winding-gear, by means Vot' the crown-wheel t.

rlhe positionof the collar m, when the winding-gear is thrown out, is shown in fig. 2.

The parts t, 7.', m, n, n', s, and t, with their connected gears and pinions, form no part of my invention. lhey are such as commonly used, and others may be substituted if found convenient.

My invention relates only to the devices necessary to 'move the push-pin 7L so as to bring into action, at pleasure, either the winding-gear onthe hand-set. f

The advantage of my improvement over. others that move into gear the hand-set by means of the position of the bow-ring on the stem is that the ordinary stemwinding movements are not changed, and the pushpin 71l is only shortened so as not to project beyond the case.

H aviug` thus described my invention,

\Vhat I claim, and desire to secure by Let-ters Patent ofthe United States, ist- The combination and arrangement ot' the lever f, and push-pinh, with sleeve d, omits equivalent, so
